My invention'relates to radiators of a general type suitable forAcooling heated mechanism b means of a forced circulation of air.

Whi e my invention admits of general use,

itis of special service in connection with radiators employed forcooling internal combustion engines, for instance, as connected with thewater jackets of engines used upon automobiles.

More articularly stated, I give my radiator the orm of a rotary fan, soconstructed and arranged that hot water, steam or the like is caused tocirculate within the blades of the fan while the latter are rotating,the

l5 radiator while in action being continuously cooled by its contactwith air which it causes to circulate. i

My invention further com rehends using m rotary radiator as` a fan, orthe purpose ofy continuously impelling free air against and around aninternal combustion engine or the like, so as to cool it by actin uponit as a fan, independently of any cooling action as a radiator.

In addition, my invention comprehends various improvements in radiatorsand parts immediately associated therewith, for the purpose ofincreasing their efficiency.

Reference is made to the drawings forma 3U ing a part of thisspecification, :and in which like reference characters indicate likeparts throughout all of the figures.

Figure 1 is a fragmentary side elevation of my improved radiator andcertain parts used therewith, as adapted for use in connection with theinternal combustion engine of an automobile.

Figure 2 is a fragmentary end elevation of the mechanism shown in Figure1.

Figure 3 is a substantially central vertical section through the ymechanism shown in Fi re 1.

igure 4 is a side elevation of the mecha# nism appearing in Figure 1, asmounted for 5 use upon the internal combustion engine of an automobile.r

Figure 5 is a cross section through one of the radiator sections havingthe form of fan blades.

5 Referring to Figure 4 the crank case appears at 6, the shaft housingat 7, a water Jacket at 8 and a countershaft' at 9.

Mounted upon the counter-shaft 9 and revoluble therewith is a pulley 10,and en agillg this pulley and driven thereby is a elt The belt 11 alsoengages a pulley 12, shown more particularly in Figure 3. The pulley 12is Acarried by and practically forms a part of arevoluble sleeve 13, e0this sleeve having a portion 14, the internal diameter of which isrelatively large, as indicated in Figure 3.

Extending concentrically through the sleeve 13 is a neck 15, having thegeneral form 65 of a cylinder, and carried' by a gear case 16.

The gear case 16 has substantially the form of a mutilated sphere, andis provided with a? upwardly extending cylindrical portion 1 Fitted intothe cylindrical portion 17 is a 70 pipe 18, which leads to and isconnected with the upper portion of the water jacket 18 as yshown moreparticularly in Figure 4.

A packing 19 having an annular form as 75 indicated in Figure 3,encircles the neck 15 and fitsinto the sleeve 13. This packing isengaged by a gland 20 of annular form, which 'encircles the neck 15 andis located within the portion 14 of the sleeve 13. so

Also located within the portion 14 is a ballv bearing, consisting ofannular members 21 and 22 separated by balls 23. vThe annular member 21engages the gland 20 and holds it against the paclnng 19.

An adjusting ring 24 is carried by the portion 14, into which it isscrewed, so as to bring it into engagement with the annular member 21 ofthe ball bearing. v

By turning the adjusting ring 24 and thus 90 moving it slightly to theright or left according to Figure 3, the pressure of the gland 2Oagainst the packing 19 may be adjusted as required.

The sleeve 13 is provided with a hub flange 95 The tubular shaft 30 isadapted to turn, as

hereinafter more fully described, the sleeve 15 being stationary.

Each hollow blade 26 is provided with a partition31, of the form shownmore particularly in Figures 3 and 5. This partition extends from thetubular shaft 30 radially outward, nearly but not quite-to the outer endof" the blade, as may be understood from Figure 3. A

By this arrangement there is formed on one side of the partition 31 aehannel`32, and on the opposite side of this partition, another channel33, these two channels being connected with each other and renderedpractically continuous by a passage 34, as indicated more particularlyin Figure 3.

The tubular shaft 30, near its outer 'orfree end, is provided with'anumber of ports 35,v

one for each blade 26, these ports being so arranged as to maintaincommunication between the passages 33 of the blades and the passagethrough the tubular shaft 30, this last mentioned passage being shown at36.

The tubular shaft 3() is so spaced from the neck 15 as to form betweenthese parts an annular passage 37, shown more particularly in Figure 3.

The hub iange 28 carries a closure plug 38, fitted into position by aidof a gasket 39.

By removing the closure plug 38, access may* be had to the passage 36vand ports 35.

' The nipple 17 is provided with a passage 40, shown more particularlyin Figure 3, and by means of this passage communication is maintainedbetween the pipe 18 and the annular passage 37.

Detachably mounted upon the tubular shaft 30 and normally revolubletherewith is a bevel gear 41, having a general annular form as indicatedin Figure 3. This bevel gear engagesa stationary shoulder 42 with whichthe gear case is provided, the shoulder servingas a bearing for thebevelgear.

' Located within the gear ease 16 and meshi ing with the bevel gear 41,is another' bevel gear 43, mounted upon a revoluble shaft 44, this shaftbeing juornaled within the gear case.

Mounted upon the lower end of thegear case is a small pum 45 of thecentrifugal type. This pump 1s connected with and driven by revolubleshaft 44. A pipe 46 extends romthe pump 45 to the bottom ofthe waterjacket 8. The pump while inaction normally `closes the gear ease 16.Byfremovy ing the closure cap 48, the operator may have access to theinterior of the gear case.

The course of the hot water to be cooled by my invention may be tracedas follows: The water being forced by the pump 45 through the pipe 46enters the bottom of the water jacket 8, which is normalll full ofwater. From the to of the water Jacket the water passes throug the pipe-18 and nipple 17, following the passage 40, shown more par' ticularlyinFigure 3, into the annular passage 37; then passing to the leftaccording t0 Figure 3, the water passes radially outwardfollowing thepassages 32 out to the passages 34 and thence radially inward, throughpassages 33 and ports 35. Thence the water follows the passage 36 intothe gear case 16, and from here it4 passes downwardly into the pump 45.

Thus there is a circulation of the water continuously so long as the um45 is in operation. It will be noted tliat t e water divides and passesthrough the several blades 26, and that in passing through each blade itgoes radially outward to the end of the blade, and thence returnsradially inward.

The radiator as a whole, comprising as it does a number of se 'tionseach having the proximate form of a an blade, has the form of a rotaryfan, which turns u on the neck 15. Because the tubular sha t 30, whichturns with the fan, extends entirely through and without regard for anystationary part. v

In other words, the sleeve 13'and parts carried by it, are as far aspossible self-contained and adjustable independently of other parts,their functions being thus greatly simplified.

A post 49, connected with the gear case 16 serves as a mounting for thisgear case and parts carried thereby.

The radiator is driven'by the belt 11, acting upon the pulley 12, thebelt 11 being driven by the pulley 10 which is turned by thecounter-shaft 9.

As shown inFigure 4, the radiator is so located relatively to the waterjacket and other parts having normally that, serving as a fan,.1t drivescontinuously a current of relativelycool air against and hightemperatures A It will be understood, that my radiator has V twodistinct functions, each general in its character. First, it acts likeany other radiator used to cool water which has been heated, except thatthe radiator turns through the air instead of the radiator beingstationary and the air bein circulated throu h and around it. Secon ,itserves as afan or supplying relatively cool air to the water jacket andcausing this air, by its contact with the water jacket,`to furtherremove heat therefrom, after the manner of an ordinary rotary fan usedfor such purpose. 7

A grating 50 may, if desired, be so positioned as to protect the fanfrom injury, and to protect persons from injury by the rotation of theblades, this feature being old and well known.

I do not limit myself to the use of my invention upon automobiles norupon internal combustion engines, nor to any particular form of mydevice, except as limited by my claim, the scope of which iscommensurate with my invention. j v
